摘要: 在格胞理论的基础上计算外磁场作用下液晶中的向列序。考虑分子短程关联后,序参数和内能对磁场强度的依赖关系与计算机模拟结果较好地符合。克服了平均场理论遇到的困难。

Abstract: The calculations of nematic order in liquid crystals with an external magnetic field are made based on the cell theory.By taking account of the molecular short range correlations,the dependences of order parameter and internal energy on magnetic strengty are in close agreement with those of the simulation.

Key words: liquid crystal, External magnetic field, Nematic order, Short range correlation
